Abstract
A method for sensing occupancy status within an automotive vehicle uses a radar sensor system, the radar sensor system includes an antenna system, at least one sensor and processing circuitry. The method comprises illuminating, using the antenna system, at least one occupiable position within the vehicle with continuous wave (CW signals), the CW signals being frequency modulated in time. At least one sensor signal (y(t,f. . . y(t,f)) reflected as a result of the CW signals, is received using at least one sensor the at least one sensor defining a plurality of receive channels (1 . . . i), each channel having a different frequency (f. . . f). Processing circuitry is operable for applying, for each receive channel (1 . . . i), DC offset removal to the corresponding sensor signal (y(t,f. . . y(t,f)) to generate a modified signal (y'(t, f) . . . y′(t,f)); and generating, based on the modified signals (y′(t, f) . . . y′(t,f)) one or more occupancy status signals, the occupancy status signal indicating a property related to said at least one occupiable position.
